SAN JOSE, Calif. (AP) _ Sharks defenseman Marcus Ragnarsson was knocked out of San Jose's game against Pittsburgh on Wednesday night after an early collision with scoring champion Jaromir Jagr.

Ragnarsson hurt his knee and didn't return. The Sharks said more information on his condition will be available Thursday.

Ragnarsson and Jagr ran into each other near San Jose's blue line just seven minutes into the game, and their knees appeared to collide.

Jagr skated away, but Ragnarsson limped to the bench. He kicked the bench gate in frustration and was taken to the locker room.

``He hit a 250-pound guy,'' Jagr said. ``But it was my mistake. I should have been more careful and not have gotten myself in that situation. Nothing happened to me, though.''

Ragnarsson teams with Mike Rathje to form the Sharks' top defensive pairing. After scoring just three goals in 63 games last season, Ragnarsson leads the Sharks' blueliners with two goals and five points in 10 games this season. His plus-minus rating of plus-9 is tops on the team.
